Overview
 
When teamed up with the Garmin Astro 220, this system will have you hunting in no time.

The Garmin DC 20, in combination with the Garmin Astro 220, pinpoints your dog's position every 5 seconds and runs for 17 hours. You can extend the battery life of the Garmin DC 20 by changing the position transmit rate from 5 to 10 or 30 seconds, enabling the Garmin DC 20 to work up to 36 hours in the field on one charge. You will know if your dog is pointing, sitting, moving or treeing. Where it's at. Where it's been. How fast it's moving and how far it's gone.

The Garmin Astro DC 20 can be added to the Astro 220 Receiver in seconds and is ready to work right out of the box. The dog tracking system additional collar comes with a harness or it may be attached to a standard 1" wide collar.

Rugged IPX7 waterproof standards means the unit can withstand accidental submersion up to 1 meter for up to 30 minutes.
